Letters Patent No. 94,505, dated September 7, 1869.

IMPROVED SLEIG-H-SHOE.

The Schedule referred to in these Letters Patent and making part of the same To all whom t't may concern Be it known that I, HENRY C. ,QVERMAN, of Ohicago, in the county of Cook, and State of Illinois, have invented a new and useful Improvement in Sleigh- Shoes and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, and the letters and figures marked thereon, which form a part of this specification, and in which- Figure 1 represents a side elevation of myimproved sleigh-shoe and runner;

Figure 2, a vertical sectional view; and

Figure 3, a top or plan view of the shoe detached from the runner;

The nature of my invention consists in making a sleigh-shoe with a recess or slot, as hereafter described, to receive a bolt-head for fastening the shoe to the runner.

To enable those skilled in the art to understand how to manufacture and use my invention, I will proceed to describe the same with particularity.

The same letters ofreferencerefer to corresponding parts in the different figures. I

Heretofore, in the manufacture of sleigh-shoes of cast-metal, they have been cast with holes extending through them. The bolt then is headed on the under side or bottom of the sleigh shoe, and passing up through the hole in the shoe, is secured to the sleighrunner in any convenient manner.

It is difficult to cast sleigh-shoes with the necessary holes in them for the bolts, without their checking or receiving a flaw to weaken them; and especially in the manufacture of chilled sleigh-shoes, it is very diflicult to make a perfect chill about the core necessary to make the hole through the shoe.

Besides the difiiculties experienced in casting and chilling sleigh-shoes with holes through them, as above described, the shoe is much weakened by the holes in them, and they are very liable to break, while in use, where the holes are.

To overcome the above difficulties and objections to cast and chilled sleighshoes, I cast the shoe with the recess or slot A, in the top of it, above the part that is chilled. The recess has an opening at one end sufficiently large to receive the head of the bolt. The shoe then being moved back, causes the head of the bolt to pass beneath the flanges above the recess, as clearly shown in fig. 2. The bolt passing through the sleigh-runner B, and being fastened by the nut C, se-

cures the shoe firmly to the runner.

There is no bolt-head'on the bottom of the shoe, and the fastening resting so firmly against the bottom of tne runner, is not liable to break out.

The shoe is readily removed and replaced by simply loosening and tightening the nuts 0.

Having fully described the construction and operation of my invention,

What I claim, and desire to secure by Letters Patent, is-

A sleigh-shoe, constructed with the recess A, for the purpose of fastening the same to the sleigh-runner, substantially as specified and shown.
